Here's what I get
Explanation:
Iron is found in hematite, an ore with the formula Fe₂O₃.
It goes into a blast furnace, where burning coke and a forced supply of air react to form mostly carbon monoxide.
C + O₂ ⟶ CO₂
C + CO₂ ⟶ 2CO
At the high temperatures inside the furnace, the carbon monoxide reduces the hematite to liquid iron.
Fe₂O₃ + 3CO ⟶ 2Fe + 3CO₂
The iron flows to the bottom of the furnace, where it is drawn off.

Answer:
Explanation:
Since the <em>rate constant</em> has units of <em>s⁻¹</em>, you can tell that the order of the reaction is 1.
Hence, the rate law is:
Solving that differential equation yields to the well known equation for the rates of a first order chemical reaction:
You know [A]₀, k, and t, thus you can calculate [A].
